In clinical work, many patients with facial spasm are diagnosed with conservative treatment and the results are not satisfactory. When they visit the doctor again, the doctor will often suggest the patient to be treated by facial nerve microvascular decompression. It is common for patients to be hesitant because they have too little information about the surgery. As a doctor, it is necessary to explain in detail here so that patients can put down their baggage and accept reasonable suggestions with a relaxed mood. First of all, MRI scan can be used to understand the nerve and blood vessel relationship before the surgery, so that the surgery can be targeted. Secondly, the operation is performed under a microscope with a clear view, which helps to protect the important surrounding nerves and blood vessels and minimize complications. In experienced treatment centers, the efficiency of the surgery is about 95% and the possibility of complications is less than 1%. Facial nerve monitoring and auditory evoked potential monitoring are used during the surgery to understand the disturbance to the nerve and determine whether the decompression is complete in a timely manner, which effectively reduces the risk of nerve injury and helps to improve the surgical efficacy. The surgical incision is small and hidden in the hairline, and the surgery basically does not bleed. The postoperative period does not affect the appearance. Timely postoperative review of head CT is beneficial to detect changes in the condition and reduce the risk. Having said that, I believe that patients and friends have a preliminary understanding of the surgery and should be in a calm mood to accept the surgical treatment, get out of the shadow brought by the disease and welcome a brand new life.
